Abstract

Securing digital assets in a vault that interfaces with multiple different third-party wallets to store keys/mnemonics. The vault interface accepts input from multiple different party wallets to combine multiple encryptions and secure storage techniques. Numerous cryptographic mechanisms are employed to securely pull a mnemonic phrase from a third-party wallet and into an institution's vault. A customer's mnemonic phrase is securely transported from a personal wallet into a secured institution's encrypted vault using the power of HSM to encrypt and decrypt a customer's mnemonic phrase securely.
